The Messenger of Allah (ﷺ) prohibited perpetual fasting. They (the people) said: You keep perpetual fasting, Messenger of Allah. He said: My position is not like that you yours. I am provided with food and drink.
Sunan Abi Dawud Book 14, Hadith 48
← Previous Hadith We broke the fast one during Ramadan when it was cloudy in the lifetime of the Messenger of Allah (ﷺ) ; then the sun rose. Abu Usamah said: I said to Hisham: Were they commanded to atone for it ? He replied: That was inevitable.

Sunan Abi Dawud Book 14, Hadith 47 Next Hadith → The Messenger of Allah (ﷺ) as saying: Do not observe perpetual fasting. If any of you wants to observe perpetual fast, he should observe it until the dawn. They (the people) asked: You observe perpetual fast ? He replied: My position is not like that of yours. There is One Who gives me to eat, and there is One who gives me to drink.
